New Revision: 195168
URL: http://svn.freebsd.org/changeset/base/195168

Log:
  Type problem when FreeBSD is in a virtualized environment, the
  result was when the RX index wrapped it was converted into some
  sort of gibberish and written into the RDT register, effectively
  killing the RX side of the thing :)
